Іджюїн Каору

He is a childhood friend of Tada and also a member of the photography club. If he doesn't open his mouth, he actually is quite handsome but sadly he can never keep it shut long enough to fool anyone. He is due to take over his family's famous restaurant in Ginza, so he is very good at cooking. When they were small, Tada saved him from a dangerous situation so he thinks of Tada as his one and only friend. Because he often spends his days at the Tada Coffee Shop, he is also good friends with Grandpa and Yui, but since he is hated strongly by Nyanko Big, he goes into self-defense mode whenever they meet.
